SAS 2: Inflammation and Disorders of Growth

Question 1

From the Latin word “inflammare” to set fire

Answer 1

Inflammation

Question 2

Universal response to tissue damage by wide range if harmful stimuli including mechanical trauma, tissue necrosis and infection.

Answer 2

Inflammation

Question 3

Changes during inflammation

Answer 3

1. Blood vessel
2. Blood stream
3. Changes in rate of flow
4. Leukotic emigration
5. Diapedesis of RBC
6. Serum exudation

Question 4

Momentary contraction of blood vessel

Answer 4

Blood vessel changes

Question 5

Vessel dilation causing atrial blood

Answer 5

Blood vessel changes

Question 6

Increase permeability of venules and capillaries. Its effect is leakage of plasma proteins, RBC and WBC

Answer 6

Blood vessel changes

Question 7

Changes in Erythrocyte distribution

Answer 7

Change in the blood stream

Question 8

Leukocyte migration (pavement). Its mechanisms is either :
a. WBC gets adhesive
b. Capillary wall gets sticky (endothelium gets sticky)

Answer 8

change in blood stream

Question 9

Accelerate of the rate due to arteriolar dilation

Answer 9

Change in rate of flow

Question 10

Retardation due to :
1. Fluid loss leads to increase blood viscosity
2. Leukocytes stickiness

Answer 10

Change in rate of flow

Question 11

Stasis: well established congestion that favors, molecular and cellular escape i.e exudation

Answer 11

Change in rate of flow

Question 12

Ameboid movement of the leukocytes towards the site of inflammation cause CHEMOTACTIC FORCES

Answer 12

Leukocytes emigration

Question 13

Process of attraction of leukocytes to certain area that has the chemotactic substances

Answer 13

Chemotaxis

Question 14

The action is phagocytic

Answer 14

Neutrophils

Question 15

It will produce pus and this process call suppuration or purulent exudate

Answer 15

Neutrophils

Question 16

Mast cell and release of histamine

Answer 16

Eosinophils

Question 17

These cells present in the parasitic infection and hypersensitivity due to release of ———– chemotactic factor from mast cells when intact with Ag+lgE to mast cells & release of histamine

Answer 17

eosinophils

Question 18

-It is phagocytes cells inside the blood & when reach to the cells and tissue it will become macrophage cells or called histiocytes

Answer 18

Monocytes

Question 19

-They fuse to form multi nucleated giant cells(Langhan’s giant cell.)

Answer 19

Monocytes

Question 20

-The function of macrophage is phagocytes foreign body
-Removed(scavengers)the debris

Answer 20

Monocytes

Question 21

It’s similar to macrophage and similar to epithelial cells close to each other with no different borders between its cytoplasm & they tend to have small nucleus

Answer 21

Epithelioid cells

Question 22

These cells are no phagocytic cells but release lysosomal enzyme.

Answer 22

Epithelioid cells

Question 23

Form by fused the cytoplasm of the macrophages(2–3 or reach to 20).

Answer 23

Giant cells

Question 24

What are the 4 types of Giant Cells?

Answer 24

1.Langhan’s giant cell
2.Foreign body giant cells
3.Touton Giant cell
4.Warthin-Finkeldy

Question 25

Phagocytic power is seen in Bacteria

Answer 25

Neutrophils
